2 What is Construction Aggregate? (Processed from naturally occurring minerals)

3 Construction Aggregate Uses Asphalt & Concrete is 80-90% Sand & Crushed Stone

4 Aggregate Industry Overview Sources of Construction Aggregate in San Diego Stadium/Poway Conglomerate Peninsula Range: Granite Rock Santiago Peak Formation: Metavolcanic Rock Alluvial Valley: Sand and Gravel

11 Million Tons San Diego County Aggregate Production vs. Demand Aggregate Production Aggregate 5.4 tons per capita Source: Population: California Department of Finance; Demand: Dept of Conservation OFR 94-08; Production: California Department of Conservation

12 Number of Active Mines Active Production Sites in San Diego County Source: USGS Minerals Yearbook, California Department of Conservation Special Report 153, 1982 & DMG OFR 96-04, 1996; and operator Reclamation Plan files.

13 San Diego County Construction Aggregate Quarries 2012

14 San Diego County Construction Aggregate Quarries 2030

15 San Diego only has 16% of the Permitted Reserves Needed for the Next 50-Years. Source: Clinkenbeard, John, P., Aggregate Sustainability in California. Department of Conservation, California Geological Survey = Permitted Reserves Remaining; 1014 = 50 year demand

16 What s the problem? A shortage of locally permitted construction aggregate resources

17 Reasons for Aggregate Shortage Number of quarries are decreasing Approval of Conflicting Land Uses Mineral Resources not protected at local level Permitting process is cost and time prohibitive

18 Land Use Constraints for Extraction Total County: 4,200 sq. miles MSCP Lands: 300 sq. miles Mineral Resources: 3 sq. miles

19 Time and Cost Prohibitive Permitting Process Property Acquisition 6 Months Anticipated Site Approval Timeline Prepare Reclamation Plan and Application 12 to 18 Months 48 to 66 Months Application/Environmental Review 24 to 36 Months Condition Compliance 6 Months Realistic Timeline Based on Recent Cases: Rosemary s Mountain (18 years) Otay Hills (10 years to date and ongoing) JB Sand (4 years and project was denied) Jamul Quarry (7 years, but could not satisfy conditions of approval)

20 How is San Diego Meeting Demand? Increasing Production at Existing Quarries Using Recycled Materials Importing from other Areas What are the impacts?

21 Production Per Quarry (1,000 short tons) Production and truck trips increase per site 5,250 4,500 3,750 3,000 2,250 1, based on 5.4 tons/capita demand 1.5 million tons/yr = 400 truck trips/day

22 Recycled Materials Helps conserve limited resources Reduces materials sent to landfills However Limited in supply and use 80% of road asphalt is currently recycled #1 recycled material by volume Source: Associated General Contractors: Federal Highway Administration

23 Recycled Material Limitations Recycled aggregates cannot be used for all construction projects. Only used for Base and Subbase material If all concrete & rubble were recycled, it would represent only 5% of total aggregates produced. Source: Recycling Today & USGS Fact Sheet FS , February 2000.

24 Importing Materials from Great Distances

25 However, Import Areas Are in Short Supply Source: Clinkenbeard, John, P., Aggregate Sustainability in California. Department of Conservation, California Geological Survey = Permitted Reserves Remaining; 1014 = 50 year demand

26 Impacts From Importing Increased Transportation Costs Keep material costs high High paying jobs are sent offshore or out of County Reduces impetus to develop resources locally and eliminates competition Increased greenhouse gas emissions Increased road congestion (VMT) and maintenance costs

27 Impacts on Greenhouse Gases Status Quo: 2.5 times more CO 2 Local Supply: 4 times less CO 2 Source: San Diego Region Aggregate Supply Study. SANDAG. Jan 2011.

28 Impacts on Fuel Consumption Local Supply: 4 times less fuel Status Quo: 2.5 times more fuel Source: San Diego Region Aggregate Supply Study. SANDAG. Jan 2011.

29 San Diego County Crisis Alert: Aggregate Supply Reduced to 10 Years Reasons for the Shortage: Fewer production sites Prior land use approvals preclude mineral extraction Mineral resources not protected Lengthy and expensive permitting process This Supply Crisis Has Created Increased: Production Per Site Truck Traffic Per Site Greenhouse Gas Emissions Transportation Costs Costs to Consumers

30 Potential Solutions Permit Additional Local Reserves Recycle

31 Benefits of Permitting Local Sites Lower Costs for Aggregate Reduced Cost for Construction Projects Lower Greenhouse Gas Emissions Reduced Traffic Congestion Reduced Road Maintenance Costs Lower Greenhouse Gas Emissions And Jobs Stay Local

32 Policy Recommendations Streamline Permitting Process General Plan Implement Mineral Resource Policies Zoning Ordinance Extractive Use Zones Require in-kind replacement (similar to habitat policies) Consider mining and reclamation to be Compatible with other resource areas.

33 Founded in 2014 by members of the construction aggregates industry, Project Cornerstone is a grassroots organization whose mission is to educate local community members, public agencies and policy makers that mineral resources are the cornerstone of our communities. We offer educational programs and community outreach presentations. The organization also offers field trips to local mining operations and in-class activities for San Diego County students.
